Edge Optical Effect as Probe of Chiral Topological Superconductor

Posted by dbos Peking

Kavli Affiliate: Jing Wang | First 5 Authors: Linghao Huang, Jing Wang, , , | Summary: We study the optical effect of chiral topological superconductors in two dimensions. The linear optical response from chiral Bogoliubov edge modes in clean superconductors has in-gap resonances, which is originated from the transitions within the edge particle-hole pair bands. […]
